New Zealand ADHD Care Gaps Persist Despite Expanded GP Prescribing Rights

Adults seeking treatment for attention deficit hyperactivity disorder in New Zealand previously faced a major bottleneck due to limited public mental health capacity and high private psychiatrist fees. That changed in February when vocationally trained general practitioners and nurse practitioners gained the authority to start adults on stimulant medication. While the reform aimed to make treatment easier to access, changing who can prescribe has exposed ongoing problems with assessment capacity, cost and training standards.

Assessment Challenges

Attention deficit hyperactivity disorder is estimated to affect between 2.5% and 3.4% of adults, and left untreated it is linked to poorer educational and employment outcomes, mental health struggles, substance use and justice system involvement. A 2022 analysis of national prescribing data found only about one in three adults under 50 with suspected the condition received stimulant medication. The new system leaves considerable discretion over how assessments are conducted in primary care. A national clinical principles framework released in 2025 mentions expertise and validated tools without setting required training or competency standards. A thorough assessment can take one to three hours, while more than 60% of adults with the condition have another overlapping condition such as anxiety, depression, post-traumatic stress disorder or autism.

Cost And Equity

Cost remains a major barrier because general practice is already stretched and standard visits are not free, meaning multi-hour assessments may still be unaffordable for many patients. This creates a risk that access depends on which practice someone attends and what they can pay rather than medical need. Māori, Pacific peoples, rural communities, people on low incomes and rainbow communities are particularly vulnerable to missing out. New models of care are emerging, including team-based approaches and expanding commercial telehealth clinics, but lack of consistency could lead to varying quality and availability. International evidence shows patients also benefit from psychoeducation, without which some may receive a prescription and little else.

Context

Health reforms often target single bottlenecks like prescription rights, but complex medical care pathways require supportive funding, training standards, and diagnostic consistency to truly improve population health outcomes. General practice networks across many healthcare systems face severe resource constraints that limit the time doctors can spend on complex, multi-hour diagnostic evaluations.
